GAS-ENGINE ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 661,854, dated November13, 1900. -Application filed December 20.1899. Serial No. 740,957.(NomudeL) To all whom, it may concern.-

Be it known that I, XAVIER DE LE CROIX, a citizen of Belgium, residingat 88 Rue Stevin, Brussels, in the Kingdom of Belgium, haveinventedcertain new and useful Improvements in Gas-Engine Attachments, (forwhich I have applied for a patent in Great Britain, dated August 4,1899, No. 15,982,) of which the following, is a specification.

An oil-motor for propelling a vehicle has in many cases its cylinder,which is open at the bottom, fixed overa casing, in which the crank andfly-wheels revolve.

My invention consists in applying to such a casing tubes for admissionand discharge of air as the pistonascends and descends without allowingescape of lubricant, as I shall describe with reference to theaccompanying drawing, which is aside view, partly sectional, of a motorhaving two air-tubes Z, according to my invention, applied to itsfiy-wheel cas ing. These tubes Z, of which one is shown in section, arefixed on the upper part of the flywheel casing e, and the interior ofeach is crossed by a number of wire-gauze partitions 'm, separated fromeach other by rings. The outer mouth of each tube has an inwardlyturnedlip, under which is fixed a deflector 12 of mushroom shape. These tubesZ allow es cape of air when the piston of the motor descends, lesseningthe capacity of the casing, and allow entrance of air when the pistonascends, in creasing the capacity of the casing. The circulation of airhas a cooling effect on the lubricant contained in the casing, so thatit does not become too fluid. The gauze partitionsfm and the deflector nand lip at the outer mouth of each tube, while they prevent oil frombeing thrown out, also prevent dust and grit from entering the casing.

Having thus described the nature of this invention and the best means Iknow of carrying the same into practical eifect, I claim In combinationwith the cranktand fly-wheel casing of an oil-motor, tubes forcirculation of air, each provided with wire-gauze partitions and at itsouter mouth a turned-in lip and a deflector, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

XAVIER DE LE OROIX.
